‘Inadvertent geoengineering’: Researchers say low-sulfur shipping rules made climate change worse

Described at the time as the "biggest change in oil market history," the International Maritime Organization enforced new standards on Jan. 1, 2020, to cut their fuel sulfur content to 0.5%, down from 3.5%.

Countries at the meeting of the United Nations' International Maritime Organization in London signed a deal for shipping emissions to reach net zero "by or around" 2050.A sweeping regulatory change in 2020 to slash air pollution from the world's ships could have played a role in boosting global average temperatures, according to the findings of a controversial study.," the International Maritime Organization enforced new standards on Jan.

Describing this as accidental geoengineering, and presenting figures which may overestimate the impacts, could lead to misguided assumptions about policies intended to curb future emissions.

However, Hirschi said the authors likely overestimated the impact the reduction of sulfur in ship fuel had on the record-breaking global temperatures witnessed last year and in 2024.
